AB*D= BE.

->EEE can be 111, 222, 333, … , 999 or we can say that… 111= 37*03, 222= 37*06 , … & so on.
So, AB=37. To get CD exactly…apply given equation to judge all possible cases. finally u will get CD=12 & AB*D=37*2 = 74 = BE.ANS IS BE.

A=3 B=7 C=1 D=2 E=4

AB*CD=EEE

@ LEEPIKA BISWAL : i just tried to find out 4 different nos whose multiplication will contain only 1 digit like 111,222,333,444,555,666,777,888,999
i found those nos in multiplication table of 37 . then i substitute alphabet with digit and found solution as

A=3 B=7 C=1 D=2 E=4

AB*CD=EEE
37*12=444

E*CD-AB=CC
4*12-37=11

Final solution
AB*D=BE
37*2=74
